Laptop was randomly turning off time to time. And then have difficulties to turn on again until on day it died.

It was not even hot (around 60°C cpu/gpu.. I was looking on MSI Afterburner).
After thus sudden blackscreen it was impossible to turn on again. I had to fiddle with power button and try random times of pressing or letting the laptop disconnected and then plugin it back.
And then without any reason it was working again, for a few hours. Then sudden black screen again…

Laptop is from 2019
Now 2023 (around 4 years later).
Laptop did the same thing but never turned on again this time…
Green Led light on the power bank is ON !

Don’t send me that link (Razer Blade does not have power, won't boot up or turn on) :

I tried all of that it is not turning on.

Thanks for your attention.

Basically the most expensive at that time.
So I guess it was around 4000euros, now it is still around 3000euros.
I have a macbookpro from 2008 that I used many years for music, 3d, graphics, Dj events and it is till working. Now everyday, my dad is using it. (that is 15 years)

This Razer Blade I’m talking about here. We are talking about an even more expensive product that I used to do same things (not DJ stuff) but 3d, graphics, Unity engine, gamedev. But now it is dead without any reason (that is around 4 years)
